I used the supertech setup supplied by Big bad Dan at Elite racing. Its a comprehensive kit inc, o/s valves, dual valve springs, solid buckets,titanium retainers etc.have had zero issues with i to date so its all good as far as I'm concerned.
The neo head is another option but it too suffers from different bolt patterns on the intake side, different coil pack etc.
It can all be done. Just depends on what stage you are at.
If i were starting from the ground up I would probably use the 26 head but as I already had my hot and cold side sorted it was easier to convert the 25 head to solid operation.
